Answer 2

a=2    b=(-5)  c = 2                                                                                                               Δ=b²-4ac                                                                                                                           Δ=(-5)²-4.2.2                                                                                                                      Δ=25-16                                                                                                                               Δ=9                                                                                                                      x=-b+-√Δ/ 2a                                                                                                                  x´=5-3/2.2a                                                                                                                   x´=2/4o 1 e 4 simplifica por 1                                                                               x´´= 5+3/2.2a                                                                                                              x´´=8/4=2                                                                                                                            s=[ 1/2]          espero ter ajudado
